Abstract
We demonstrate that an appropriate discretization scheme can render the convergence of the coupled-dipole approximation (also known as the discrete-dipole approximation) much more regular and improve its accuracy by as much as a factor of 24. This discretization scheme is simple, can be applied to arbitrarily shaped scatterers, and does not require additional computation time.
摘要
我们证明，一种合适的离散化方案可以使耦合偶极子近似（也称为离散偶极子近似）的收敛性更加规则，并将其精度提高多达24倍。这种离散化方案很简单，可以应用于任意形状的散射体，并且不需要额外的计算时间。
